    Hello Everyone,

    Can anyone help me regarding the following questions?

    Name the regulatory enzyme in the following metabolic pathways-

    a. Bile acid synthesis.
    b. Citric acid
    c. De novo synthesis of palmitate.
    d. Urea cycle.
    e. a^ - oxidation of fatty acids.
    f. Glycolysis.
    g. Cholesterol synthesis.
    h. Pyrimidine biosynthesis.

    I am also trying to find outthe answers, but if anybody knows the
    answers, kindly help me.

    Regards,
    Kiru.

    Biochemistry homework?

    The first link after entering <"bile acid" +synthesis +"regulatory enzyme">
    in google gives:

    "Two key regulatory enzymes in the bile acid biosynthesis pathway are
    cholesterol 7alpha-hydroxylase/CYP7A1 (7-hydroxylase) and sterol
    12alpha-hydroxylase/CYP8B1 (12alpha-hydroxylase). [...]"

    You will most probably find the others in the same manner.

    Hello,

    I got the answers.Thank you very much for your reply. I could not get
    the answer for the first question only. You helped me get it. Thank you
    once again.
    The answers are as follows,

    i) Cholesterol 7 alpha hydroxylase &
    Sterol 12 alpha hydroxylase.
    ii) Citrate synthase, isocitrate dehydrogenase and alpha keto glutarate
    dehydrogenase.
    iii) acetyl CoA carboxylase.
    iv) Carbomoyl phosphate synthetase I
    v) Delta^3 cis or Delta^2 trans enoyl CoA isomerase and 2,4 dienoyl CoA
    reductase.
    vi) Hexokinase, phosphofructokinase - I and pyruvate kinase.
    vii) 3-hydroxy 3-methylglutaryl-CoA reductase(HMGR)
    viii) Carbamoyl phosphate synthetase-II

    Thanks & Regards,
    Kiru.
